How Much Is a Gold Filling Worth?
Dental gold fillings, crowns, inlays, and onlays are among the most valuable everyday scrap precious metal items people recover from dental extractions. Because dental gold is fabricated from specialized high-purity noble metal alloys, an average extracted gold filling or crown is typically worth between $40 and $250 in cash. Total liquidation payout depends heavily on the physical gram weight of the piece, the exact dental gold alloy purity (typically 10-karat to 18-karat), and current international gold spot prices.
Dental Gold Alloys and Karat Purity Percentages
Dental restorations are never made of pure 24-karat gold because pure gold is far too soft to endure repetitive biting forces exceeding 200 pounds per square inch. Dental laboratories utilize specialized Class High-Noble alloys meeting American Dental Association (ADA) standards. High-noble dental alloys contain at least 60 percent noble metals, with a minimum of 40 percent pure gold (roughly equivalent to 10k to 18k jewelry gold).
The remaining alloy consists of valuable platinum group metals—such as platinum and palladium—alongside strengthening base metals like copper, silver, and zinc. High-noble yellow gold crowns typically test between 16-karat (67% gold) and 18-karat (75% gold) purity. Budget white dental crowns (Porcelain-Fused-to-Metal, or PFM) often utilize silver-palladium or non-precious nickel-chromium base alloys, which hold significantly lower precious metal scrap value.
Compare scrap melt values for dental gold fillings across weight and alloy purity benchmarks:
| Restoration Type & Alloy | Average Weight (Grams) | Estimated Gold Karat Purity | Melt Value ($72/g Spot) | Typical Cash Offer |
|---|---|---|---|---|
| Small Occlusal Gold Inlay | 1.0 to 1.5 Grams | 14k to 16k (58% to 67%) | $42.00 to $68.00 | $32.00 to $55.00 |
| Standard Molar Gold Filling | 2.0 to 3.0 Grams | 14k to 16k (58% to 67%) | $84.00 to $136.00 | $65.00 to $110.00 |
| Full Cast Yellow Gold Crown | 3.5 to 5.5 Grams | 16k to 18k (67% to 75%) | $169.00 to $297.00 | $135.00 to $240.00 |
| Large Multi-Unit Gold Bridge | 7.0 to 12.0 Grams | 14k to 16k (58% to 67%) | $294.00 to $545.00 | $230.00 to $440.00 |
| White PFM Crown (Palladium Base) | 3.0 to 5.0 Grams | 0% Gold (Palladium/Silver) | $25.00 to $65.00 | $15.00 to $45.00 |
Tooth Debris, Porcelain Weight, and Smelting Deductions
A common mistake when weighing an extracted gold filling or crown is weighing the entire object on a home scale without accounting for non-metallic debris. Extracted dental restorations frequently contain cement, calcified biological tooth roots, and baked ceramic porcelain overlays. These non-metallic components add deceptive weight but zero precious metal value.
Professional precious metal refiners place dental scrap into high-temperature melting crucibles with chemical flux, burning off organic tooth matter, cement, and porcelain slag. The resulting pure alloy button is then tested via X-ray fluorescence (XRF) spectrometry to measure exact percentages of gold, silver, and platinum. Scrap buyers typically deduct thirty to fifty percent from the gross scale weight of a dirty crown to account for attached porcelain and cement.
Review typical payout expectations across secondary buyers for dental gold scrap:
| Dental Gold Buyer Channel | Typical Payout % of Assay | Estimated Cash for 4g 16k Crown | Key Advantages & Risks |
|---|---|---|---|
| Specialized Dental Refiner (Mail-in) | 85% to 92% of Assay | $165 to $180 | Highest payout, provides full elemental assay report |
| Local Coin & Bullion Shop | 75% to 85% of Melt | $145 to $165 | Instant in-person cash payment, safe transaction |
| Local Retail Jeweler | 65% to 75% of Melt | $125 to $145 | Immediate cash, but many lack dental testing equipment |
| Traditional Pawn Shop | 50% to 65% of Melt | $95 to $125 | Lowest cash payout, heavily discounts for tooth debris |
| Cash-for-Gold Mall Kiosks | 40% to 60% of Melt | $75 to $115 | Very low payouts, predatory pricing models |
Selling Dental Gold for Maximum Cash Payout
When a dentist removes a gold crown or filling, remember that the extracted precious metal legally belongs to you, not the dental practice. Always ask your dentist to place the extracted restoration in a small envelope for you to take home. Leaving dental gold behind forfeits substantial cash equity that offices collect and recycle in bulk for profit.
To maximize cash recovery, bypass general pawn shops and mall kiosks that lack X-ray fluorescence analyzers and guess low on karat purity. Instead, sell to a certified local coin shop or mail your piece to a dedicated dental precious metals refiner (such as Garfield Refining or Midwest Refineries). These specialized refiners melt the piece cleanly and pay based on exact laboratory assay assays, often reimbursing for valuable palladium content alongside gold.
How to Value and Sell an Extracted Gold Filling in 5 Steps
Follow these five steps to clean tooth debris, calculate gold weight, test purity, and sell dental scrap.
Request Extracted Metal from Your Dentist
Inform your dentist before extraction that you wish to keep your removed gold crown or filling, taking it home in a sealed container.
Clean Away Biological Debris Safely
Soak the restoration in rubbing alcohol or mild detergent to sanitize, using a soft toothbrush to remove loose cement.
Weigh the Restoration on a Gram Scale
Weigh the clean restoration in grams on a digital scale, estimating that 20% to 40% may consist of ceramic porcelain or core cement.
Look Up Current Live Gold Spot Price
Check the live market price of gold per gram, estimating that high-noble yellow dental crowns average 16k (67%) purity.
Sell to a Bullion Dealer or Dental Refiner
Submit your scrap to an accredited bullion dealer or precious metal refiner utilizing XRF spectrometry to ensure fair assay payouts.
Frequently Asked Questions (8 Questions Answered)
Q1: Is a gold filling real gold?
Yes, dental gold fillings are made from real high-noble gold alloys containing between 40 and 75 percent pure gold (10k to 18k purity).
Q2: Can you legally keep your gold filling after extraction?
Yes, legally the extracted gold crown or filling is your personal property; you simply need to ask your dentist to return it to you.
Q3: How much is an average gold crown worth?
An average adult molar gold crown weighs roughly 4 to 5 grams and is worth between $120 and $250 depending on live gold spot prices.
Q4: Why do dentists use gold instead of pure porcelain?
Gold alloys have a coefficient of thermal expansion matching natural enamel, do not chip or crack, and cause minimal wear on opposing teeth.
Q5: Will a pawn shop buy a tooth with gold in it?
Yes, pawn shops routinely buy dental gold, but they will heavily discount the payout to account for the weight of attached tooth bone and cement.
Q6: Does dental gold contain platinum or palladium?
Yes, high-noble dental alloys frequently contain 5 to 15 percent palladium or platinum, adding additional precious metal value.
Q7: What is the best way to clean an extracted gold crown?
Soak the crown in boiling water or rubbing alcohol to disinfect; do not use harsh acids at home that release toxic fumes.
Q8: What happens if a dental crown has white porcelain on it?
Porcelain-fused-to-metal (PFM) crowns have a metal core beneath ceramic; refiners melt the unit and burn away the porcelain slag.
